CHURN-CLOSING DEVICE.

SPECIFICATION forming part of Letters Patent No. 338,006, dated March 16, 1886.

Application filed October 8, 1885. Serial No. 179,295.

To aZZ whom it may concern.-

Be it known that I, JOHN H. WEBER, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Churn-Closing Devices; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and novel improvements in churn-closing devices; and the invention consists in the peculiar construction of devices for closing the mouth of the churn, all as more fully described and claimed.

Figure 1 is a central longitudinal section through my improved device. Fig. 2 is a cross-section on the line 0000, Fig. 1. Fig. 3 is a plan view with the cover closed. Fig. 4 represents in plan the various styles of heaters.

In the accompanying drawings, which form a part of this specification, A represents the body of the churn, consisting of a tight barrel, upon each end or head of which is secured a proper trunnion or journal, B, designed to be received in suitable bearings in a supportingframe, 0, one of such trunnions being adapted to receive a crank-handle, O, by means of which the churn is rotated.

In the side of the body A, I form an elongated opening or mouth, D, the edges of which are protected by a flanged rim, E, which forms a seat for the cover F. This cover F is provided with an inwardly-projecting flange, a,

outside of which is placed a packing-ring, b, which, when the cover is closed, seats upon the rim F, forming an air-tight joint. Upon the outer face of the cover is secured a stud, G, formed into ears, between which is pivotally secured a locking-lever, G, one end of which is pivotally secured between ears H, secured to the body of the churn at one side of the mouth-opening. Upon the opposite side of the mouth-opening there is secured to the body of the churn a stud, 1, upon which is properly sleeved the cam-head K of the lever J, the head or rim of such cam projecting sufficiently to engage with the free end of the lever G when the latter is closed, there being (No model.)

heads or ends thereof, are rigidly secured the grooved blocks L, preferably at equal distances apart, the grooves of such blocks being designed to receive the ends of the beaterblades M, N, and O. The beater-blade M is provided with numerous circular perforations, d, the blade N with longitudinal slots e, and the blade 0 with vertical or cross slots f, as shown in Fig. 4.

At any suitable point in the body of the churn is placed a safety-valve, I, the spring 9 of which keeps the valve closed against its seat, as shown.

In providing the beater-blades with perforations of different shapes the churning is much more easily effected, as the globules are the more rapidly separated from the cream.

The blades are easily removed for the purpose of cleaning. The cover is adapted to be closed with an air-tight joint, thus preventing the escape of milk or cream; and in providing an escape valve the churn can be thoroughly washed out with hot water without fear of bursting from expansion.

\Vhat I claim as my invention is 1. The combination, with the churn-body A, cover F, and lever G, pivoted on the cover,

and having one end pivotally secured to said body, of the cam-lever J, having head K, provided with slot 0, and pivoted on said body. and arranged to engage with the free end of the lever G, substantially as and for the purpose specified.

2. In a churn, the combination, with the body A, having opening D, ring E, packing b, and cover F, having flange a, of the lever G, pivoted to said cover, with one end pivotally connected with the body, and the camlever J, pivoted on said body in proximity to the free end of the lever G, substantially as and for the purpose specified.

JOHN H. WEBER.
